I've owned about 8 240's in the last 10-15 yrs but never a 740. I belive mechanical parts-wise they have a great deal in common. I'm looking at a 1990 740 turbo wagon with new tires, new front rotors & pads, rebuilt tranny, new Air Mass Meter, sunroof, leather interior, 185k miles. It has some rust on the lower passenger doors, but otherwise is in good condition. It does need a tie rod end (then alignment). I've looked at Edmunds, NADA, and Kelley Blue Book and have found prices from $800 to $2600. Edmunds knocked off $800 due to the mileage, others $0. I figure to subtract $400 or so for the tie rod end and rust. Can I get some feedback on how much people think this is worth? I'm in Northeast Ohio. Also how long do turbos last, and how to test if the car just seems to run fine? Oil has been changed and car taken care of. What's the cost when they do go? That's my biggest concern. Thanks for the feedback!
